LXDE as default desktop

I'm using fedora 20, and I like very light desktop managers. One of my favorite is LXDE.
If you didn't install LXDE spin you have to install this desktop by yourself.

# yum install @lxde-desktop

// setup default display manager

# cd /etc/systemd/system;
# unlink display-manager.service
# ln -s /usr/lib/systemd/system/lxdm.service display-manager.service

// is someone don't like to write password
# vim /etc/lxdm/lxdm.conf

// uncomment and change line
autologin=username

// reboot and enjoy!
